color management -- strange!
Posted: Mon Oct 04, 2010 7:33 am
hoping i chose the correct forum here.
I have a strange 'problem' with color management ...
I use hueyPro to calibrate my Apple Cinema display, and to monitor ambient light.
I use X-Rite passport checker to calibrate (both my NEX-3 and my alpha 350) in various lighting environments.
But I find that a certain 'tweak' (see below) which I have saved as a preset in Lightroom usually makes the colors more accurate (when I visually check the colors of the passport beside the display).
This really shouldn't be necessary! The interesting thing is that the exact same 'tweaking' helps the NEX-3 and a350 in precisely the same manner...
I'm having trouble trouble-shooting! Lots of possibilities -- i've only thrown away the possibility of a problem with X-rite, although... maybe I'm wrong ! i'm certain there isn't a problem with LIGHTROOM, since exporting the images to other apps yields no hue changes.
1) hueyPro isn't doing its job quite right???
2) Sony sensors (at least on the NEX-3 and a350 both) have a different gamut range than my display, significant enough that... errgh
3) the Cinema display or driver is gibbled?
anyway, here's what has been "improving" my color-accuracy:
* red hue -4
* purple hue +36
* magenta hue +98
* red saturation +20
* blue saturation -17
* red luminance +10
* blue luminance -13
